There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

The peat moss, or Sphagnum, that grows in hummocks (small hills) and hollows (small valleys) are two different species. Over the millennia, they have produced large underground stores of soil carbon. These may prove to be stable in the face of global warming and may not convert in significant volumes to greenhouse gasses, a new study says. Credit: Georgia Tech / Ben Brumfield
